Can't find the original thread I was reading on this, but here's my story:

Took my 2010 Lariat SCREW in for 2nd oil change and tire rotation and told them I wanted them to turn on the DRL (per what I had read somewhere in this forum). They told me they never heard of such a thing, but would check into it. Sure enough, when I picked the truck up after work, the DRL was working. They charged me $19.95 for them to learn how to turn it on!

 

nice, this is the first Ive read of them turning them outside of factory. Thats really cool. Congrats.

 

I think the original tread was written from someone in Canada. I think it is a Canadian law to have day running lights. more guys will add to this.

 

I had asked a similar question, on a different forum, however I want to turn them off and run the fogs as the DTRL.
So this can be done through the puter at the stealer?

 

Great news... if they can be turned on (most likely in the computer), then does that mean they can be turned off? Or at the very least, change the DRL's to the park lamps as so many other manufacturer's have done?

 

I believe you are correct. My Work Order reads as follows:

"Tech connected IDS. Tech was able to program parameters in the Daytime Running Lights Module to turn them on."
